3. Focus frame only - Again, nothing untoward, just provides an uncluttered view of the image.

4. Live image only - provides a clear view of the image.

Now, it becomes a little tricky:

Press the shift button, on the side of the camera, and the i+ button at the same time to obtain two additional displays as follows:

1. Grid - I presume this is useful for composition. Proper placement of characters or objects within the image as well as proper orientation. If this is not so, please correct me.

2. Scale - This is the biggie! I cannot think how this might be useful. The scale does not change as the zoom is employed and there are no markings to the scale. If you have ideas how this might be used, I would appreciate any ideas.
